COMBINATION TOOL.

SPECIFICATION forming part of Letters Patent No. 363,331, dated May 1'7,18:87.

Application filed November 19, 1886. Serial No. 219,367. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J. HAMMER, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a certain new anduseful Combination-Tool, of which the following is a specification.

The object of my invention is to provide a combinationtool adapted forthe use of those engaged in electrical work, and especially in wiringbuildings for electrical purposes, in which those implements mostfrequently used in such operations are combined into one tool of asimple, effective, and convenient construction.

My invention consists in the novel devices and combinations of devicesemployed by me in accomplishing the above-named object, as hereinafterdescribed and claimed.

My combination-tool, in its preferred form, comprises a screwdriver,wire-cleaner, Birmingham or other wiregage, comparative measure ofinches and millimeters, and combination-wrench.

The invention is illustrated in the accompanying drawings.

Figure 1 is a view in elevation of the preferred form thereof; Fig. 2, asimilar View showing the opposite side from that seen in Fig. 1; Fig. 3,a side view of the same; Fig. 4., a bottom view; Fig. 5, a section onthe line at .r of Fig. 1, looking from below; and Fig. 6, a View of amodified form of my invention.

The instrument is made in one piece, of steel or other suitable metal.

The handle or body A of the tool is (in the preferred form) a flat striphaving one straight edge, which on one side of the strip is graduated ininches, Fig. 3, and on the other side in millimeters, Fig. 1. In theopposite edge of the handle are a series of openings, a a, communicatingwith circular apertures b I), the diameters of the openingscorresponding with the sizes of wires commonly in use, accordingpreferably with the Birmingham wire-gage. The gage-numbers are markedupon the handle. The gage thus formed may be applied to a wire at anypoint thereof, the size of the wire being determined by passing itthrough the openings a a.

Below the handle the tool is contracted into the wire-cleaner B, theedges of which are ground sharp and the purpose of which is to scrapethe insulation from wires for the purpose of making electricalconnections. Beneath the wire-cleaner B the implement terminates in ascrew-driver, C. At the other end of the instrument is a head, D, inwhich are formed squared openings 0 c, of different sizes, which formwrenches adapted for different sizes of nuts.

In the modified form of my invention illustrated in Fig. 6, thewire-gage is formed by apertures through the center of the handle orbody A, through which the ends of wires may be passed. In this form theinch-scale and millimeter-scale areplaced on opposite edges on the sameside of the handle. The wire-cleaner and screw-driver are as alreadydescribed. The head in this form is shown as a single wrench.

WVhat I claim isl. A tool for electrical work, made of one piece ofmetal, and having as a handle a flat strip adapted to be used formeasuring, and provided with openings forming a wire-gage, a head at oneend of the handle, provided with one or more squared openings adapted tobe used as wrenches, a screw-driver at the other end of the handle, anda portion between said handle and screw-driver, having sharpened edgesand forming a wirecleaner, substantially as set forth.

2. The combination-tool, made of one piece of metal, and comprising theflat body or handle A, having the graduated straight-edge,

and the wire-gage openings in the other edge, the screw-driver C,theintermediate sharpened edges forming the wire-cleaner B, and the headD, provided with the wrench-openings c, all combined and arrangedsubstantially as shown and described.
